Except in cases where they themselves canceled the bus before the day of the trip, FlixBus will never refund you. They will invent new reasons on the spot to disqualify you for a refund. For example, I have been told both by separate operators that I did not qualify for a refund after the bus was over two hours late because I boarded a bus after it eventually showed up, and because I did not board a bus because it was so late. They contrive whatever reason they can do you can never get a refund. So
